Do we know if there is an end to space?

The short answer is we don't know. We know the observable universe

observable universe

The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of ...

Observable universe - Wikipedia

— the part we can visibly see and measure — began around 13.8 billion years ago with the Big Bang.

Do we know if space ends?

No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.

How do we know where space ends?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.

Is there no end to space?

In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

What is beyond the end of space?

If the universe is infinite, there is nothing beyond it, by definition. A finite expanding universe conjures up the idea that it would have a boundary or edge, separating it from something beyond.

Voyager Just Sent This TERRIFYING New Message Back To Earth!

Does space go on forever?

The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding). The observable universe is centred on us.

Who created the universe?

Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.

What happens after space ends?

As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Eventually black holes will dominate the universe, which themselves will disappear over time as they emit Hawking radiation.

Is anything completely still in space?

If you mean 'absolutely' in the sense of 'completely', then no. The celebrated uncertainty principle of quantum mechanics shows that the more precisely we try to pin down the exact location of anything to tell if it's stationary, the more it jitters about.

Why don't we age in space?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.

What is the farthest thing in space?

The galaxy candidate HD1 is the farthest object in the universe (Image credit: Harikane et al.) A possible galaxy that exists some 13.5 billion light-years from Earth has broken the record for farthest astronomical object ever seen.

Can the universe be infinite?

The curvature of the cosmos

If the universe is perfectly geometrically flat, then it can be infinite. If it's curved, like Earth's surface, then it has finite volume. Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat.

What does space smell like?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.

Will the universe be reborn after it dies?

Observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".

Why can't we see stars in space?

The answer: The stars are there, they're just too faint to show up.

Is there still a black hole in space?

Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas.

Will we ever travel to another galaxy?

Intergalactic distances are roughly a hundred-thousandfold (five orders of magnitude) greater than their interstellar counterparts. The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction.

What is bigger than universe?

No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.

How old will the universe be when it dies?

According to the formulas used to calculate cutoffs, a universe that is 13.7 billion years old will reach its cutoff in about 5 billion years, his team concludes. For most people, the idea that a mathematical tool could be elevated to a real-world event might seem strange, but there are precedents for it in physics.

Is there a wall at the end of space?

It's a galaxy filament, a huge formation of galaxies that forms a border between the empty spaces of cosmic voids that together form the cosmic web. Hence, we call it a wall. Other, larger such walls are known. The largest is the Hercules-Corona Borealis Great Wall, which spans 9.7 billion light-years.

Who created the God?

We ask, "If all things have a creator, then who created God?" Actually, only created things have a creator, so it's improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.

Was God created by the universe?

In the Bible it says that 'God created the heavens and the earth' which shows that god created everything. Furthermore, it also says in the Bible that 'the earth was formless and empty'.

How long is 1 hour in space?

Explanation: The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. One hour on Earth is 0.0026 seconds in space. Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space.

What created space?

Today our universe encompasses many billions of galaxies, and its history can be recounted back to its earliest moments. Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed.
